  7. Surface Finishing: Apply a surface finish to protect the copper traces from oxidation, improve solderability, and enhance overall PCB reliability. Common surface finishes include solder mask, hot air leveling (HASL), immersion silver, immersion tin, and gold plating.
  8. Mini LED Placement and Soldering: Mount Mini LED chips onto the PCB substrate using surface mount technology (SMT) or other appropriate methods. Precision placement equipment is used to accurately position the Mini LEDs on the designated pads, followed by soldering to create electrical connections.
  9. Assembly and Testing: Complete the assembly of additional components, such as resistors, capacitors, and connectors, as required by the PCB design. Conduct thorough testing and inspection of the Mini LED PCBs to verify electrical continuity, functionality, and quality before final deployment.
  10. Packaging and Delivery: Package the finished Mini LED PCBs according to customer specifications and shipping requirements. Ensure proper handling and protection during transit to prevent damage or contamination.

By following these steps, manufacturers can fabricate high-quality Mini LED PCBs suitable for various applications, including displays, lighting, automotive, and consumer electronics.
